UFC bantamweight Nick Denis has announced his MMA retirement.
The 29-year-old Canadian fighter, who made an impressive UFC debut earlier this year, made the announcement on Thursday on his personal blog.
Denis cited concerns over potential brain injuries.
Denis (11-3 MMA, 1-1 UFC) signed with the UFC after posting a 10-2 record in organizations such as World Victory Road/Sengoku and KOTC. Then, in his UFC debut, he scored a 22-second knockout of Joseph Sandoval via stinging standing elbow strikes. But then came a submission loss to Roland Delorme in May in a back-and-forth bout.
Even before that defeat, Denis, a former Ph.D. student in biochemistry, had begun research into brain injuries following an especially vicious knockout loss to Marlon Sandro in 2009. LINK
